Technological equipment does not break down overnight. Before failing, it gives signals: it overheats, the disk starts to slow down, intermittent errors appear. The problem is that without a maintenance plan, those signs go unnoticed until it is too late.
What is Preventive Maintenance?
Preventive maintenance is a set of planned actions carried out regularly to keep IT systems in optimal condition. Unlike corrective maintenance — which acts after the failure — preventive maintenance anticipates problems before they occur.
What does it include?
- Physical cleaning of servers, switches, workstations and network equipment
- Disk health monitoring (SMART, fragmentation, read/write errors)
- OS and software updates (security patches, drivers, firmware)
- Backup verification: that the copies work and can be restored
- Security review: outdated antivirus, open ports, weak passwords
- Performance analysis: CPU, RAM and storage usage
Why is it critical for your company?
A single hour of downtime can cost thousands of dollars in productivity, lost sales or support costs. Most of those incidents were preventable.
At Zelarus we implement preventive maintenance plans adapted to each company, with reports and alerts so you always know the state of your infrastructure.
